MANURE LOADER.

Application filed May 25,

To all whom t may concern Be it known that I, WLLrAM OTTo,a citizen of the United States, residing at Algoma, in the county of Kewaunee and State of Wisconsin, have invented certain new and useful Improvements in Manure Loaders, of which the following is a specification.

The invention relates to a loading machine and more particularly to the class of manure loaders.

The primary object of the invention is the provision of a machine of this character, wherein a pile of material such as manure or the like can be conveyed into a wagon or other conveyance without requiring manual labor, the machine being adjustable to permit the conveyor, mechanism to be shifted relative to the pile` as the bulk thereof decreases, and, thus in this manner avoid the constant changing of the position of the machine in its entirety and the material continuously fed to the wagon or other receiving vehicle until the mass or pile has entirely diminished.

Another object of the invention is the provision of a machine of this character, wherein the conveyor mechanism can be extended or retracted and likewise the feed forks can be adjusted to regulate the extent of throw or movement thereof, thus it being seen that said forks will be operable on themaximum of the pile of material at one setting of the machine.

r provision of a machine of this character which is novel in form, construction and operation so as to render the same effective for the handling of piled material irrespective lof the volume or height thereof.

A still further object of the invention is the provision of a machine of this character which is comparatively simple in construction, readily portable, thoroughly reliable and eiiicient in its purpose, strong so as to sustain maximum loads and inexpensive to manufacture as well as durable.

With these and other objects in view, the invention consists in the:y feature of construction, combination and arrangement of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed ont in the claims hereunto appended.

In the, accompanying drawings: Y

Similar reference cha'ractersvindicate corresponding L parts throughout lthe several views in the drawings.

Referring to the drawings in detail, A, designates generally the bed of a` vwheel truck having the front guide wheels 10, and rear ground wheels 11, so as torender said truck mobile, the front guide wheels 10, being fitted to an axle B, provided with a draft tongue 12, for thev bitching of dra-ft animals thereto,` whereby said track can be drawn from one locality to another. *.Adapted to be mounted on thel forwardvr part of the bed A, of the truck is a. suitable gas engine 13, constituting the power plant of the machine. i f

Mounted upon the bed A, of the truck at the rear end portion thereof is a circular grooved track 14, in which travel the bearing rollers 15, for a turn table 16, superposed above the bed A, for supporting the loading mechanismV ofthe machine hereinafter fully described.

Secured to the under side of the turn table 16, is a circularrack gear 17, with which meshes a rack pinion 18, fixed `to the tnrningshaft 19, journaled centrally of the bed A, and this shaft is disposed longitudinally in a forward direction to the bedand has fixed to its forward end a hand operable wheel 2O to be manually actuated for the rotation of turn table 16, as will be apparent.

Extending vertically and centrally through` the turn table is a driven shaft 21, the lower end being fitted with a beveled pinion 22 meshing with a beveled gear 23, fixed to the inner end of a horizontal shaft 24, journaled transversely in the truck bed A, with its outer end projected. beyond one side of the latter and havingv fixed thereto a belt pulley 25 over which is trained a belt 27, driven from thepowerpulley C. of the engine 13 as is shown in Figure 1,-of the drawings i Y with which `mesh rack ypinions-4n Mounted upon the turn table 16, is ak support 28, fora rearwardly inclined sta# tionary conveyor frame 29, having mounted therein in the lower portion of the'same an i Y endless conveyor 30, provided with cross fiights31, at determined intervals thereof, and this conveyor-has its lower stretch mov# Vable in the support 28, over idle sprockets 32, while the forward power shaft- 33, for theconveyor 30, has fixed thereto, a sprocket wheel 34, over which is ytrainedan endless sprocket chain 35, the V'same being -Y also trained over a sprocket wheel ,36, fixed to a AMounted vin the stationary conveyor frame 29, is a slidable conveyor frame `4G which isy movable upon guide rollers 41, mountedfin,

the rear end of theconveyory frame 29, while suitably mounted at the forward end of the shdable conveyor frame`40, isa carriage 42,

slidably fitted in slots 43,"formed in oppo-` site sides Vin theV stationary conveyor frameV 29, whileupon the top edges of the/sides of thelatter frame 29 are "toothed rack bars 44, xed to a countershaft 46, suitably journaled upon the forward end of the slidable y.conveyor frame 40, the shaft-46, being also fitted with' a sprocket 47, over which is trained a sprocket chain 48,7the same .being also trainedover a sprocket 49 on ahand wheel shaft 50, having a hand wheel 51, which isrmanually op! erated so that in this manner the slidable conveyor can be extended orvretracted rela- Y tive to theV stationary framer 29, for a purpose presently described.

Arranged within the lower portion of the slidable 4conveyorframe 4f), is an Vendless conveyor 52,' the same being trained. over i sprockets D, and E, respectively, 'which sprockets E, are carried on a forwardpower shaft V53, for driving said conveyor. nTheI shaft 53, is further provided with a sprocket wheel 54,` meshing with a power sprocket chain 55, trained over sprocket: gears 56 and 57, respectively, the shaft forrthe latter being fitted with a sprocket wheel`58, over which is trained an endless sprocket chain 59, which` 1s also trained ,over a sprocketsV wheel 60,`on the power' shaft 33, ofthe conveyor 30, so that motion from theV latter will be transmitted to the conveyorr52. Y f The upper stretch of the chain 55, is held in engagement with the gear 54, through the medium` of a `chain retaining device, in the form of spaced idle rollers 61, located on opposite sides of thepointof engagementv of the gear 54, with the chain 55, the rollers being journaled on a suitable bracket l?, pivoted on the side of theframe 40, as shown in Figure `1, of the drawings. r

0n thev conveyor frame 40,is a swinging top section 62, the hangers G, therefor being journaled on the shaft H, from which point thesection 62, swings. yThis section 62, has fitted thereon bearings 63, in which is journaled a cranked shaft 64, while spaced from these bearings 63, are slotted guides `65, se-

curedV to said section, andin these guides are slidably mounted cross-heads 66, v to which are pivotally connected oscillating Vfork arms 67,- whieh project rbeyond the rear end of the machine, and have fixed in the outer ends thereof tinesor forks 68, the same being detachably mounted on the arms 67 byv means of fasteners 69.

lThe fork arms 67, are engaged in the 'cranks 'of the crank shaft 64, soV that the same may alternately be moved up and down and in and out relative to theV adjustable Y screen frame 40. The cranked shaft 64,'has fixed at one end a sprocket 70, over which is trained a sprocket chain 71, the same'be'-` ing also trained over a sprocket 72 which is operated by a gear 73, kmeshing with Va companion gear 74operated by a sprocket f7 5 over which is trained aysprocket chain 76, the)l latter being also trained overa sprocket wheel 77, on the power shaft 53, for the conveyor 52, so that motion will be Aimparted to the crankshaft for operating the fork arms. y Connected to the swinging section 62, of the slidable conveyor frame 40, are vertically disposed rackmembers 78, with which mesh rack pinions 79, fixed to a shaft 80, journaled upon stationary vuprights 81, rising from the rearend of the slidable conveyorY frame 40, and this shaft has fixed 'thereto a sprocket gear, 82, over which isV trained an endless sprocket chain V'83, the

same'being also trained overa sprocket gear 84, fixed to a hand wheel shaft 85, mqunted in suitable bearings 86, on the frame40, the shaft'85, being fixed with a hand ,wheel 87, so ythat when manually manipulated, the rack members 78, maybe raised and lowered to vary the angular Apitchof theswinging sections 62, and thereby properly positioned l the-.forks 68, relative to a pile of material kfor the raking thereof into the adjustable conveyor frame'40, for the, conveying of Ythe load by theconveyor. 52, into the stationary frame'29, and thenceby `the conveyor 30, into a/wagon body 88, for the loading of the same.

The rack members 78, arel held against the Zrack pinion 79, by means of guide rollers 89, suitably constructed and arranged on the standards 81, thus maintaining the rack members in meshing engagement with ,the rack pinions hereinbefore set forth.

'Now from'the foregoing description it will be clearly apparent that the loading machine has a maximum radius of action as by means of the turn-table the forks 68, can be swung through a radius of 180 degrees and by means of the pinions 45, the conveyor 40, is shifted in and out relative to the frame 29, the length of the racks 4a, while by means of the rack members 78 to raise and lower the swinging section 62, the forks are adjusted up and down the length of said racks to vary the throw of said forks, so that the machine is capable of operation on the maximum of a pile of material at one setting of the truck A.

The forks 68, are cleaned in their movement automatically at each revolution by extended end 91 of the swinging section 62, as on the full inward stroke and the continued upward movement of the arms 67, the forks 68, will scrape on this extended end 91, of the section 62, and thus the Inaterial clinging to said forks will be removed therefrom for the cleaning thereof.

From the foregoing it is thought that the construction and manner of operation of the machine will vbe clearly understood,l and therefore, a more extended explanation has been omitted.

What is claimed is:

l. A machine of the character described comprising a wheeled truck, a turn table supported thereon, a rearwardly inclined stationary conveyor constructed and arranged upon the turn table, an extensibly slidable conveyor constructed and arranged upon the stationary conveyor, a tilting section on said slidable conveyor, means for adjusting the section, and loading mechanism on said section.
